Update: this morning I got a courteous apology from the “General Aviation Center” of the Marechaussee, that my GENDEC was not correctly distributed at Seppe.
Wow, apologies are normally not in the official procedures book, I am surprised!
@Bluebeard: good to hear that you got the apology. The essence of what I wrote on that blog post is that software has been written by several parties to accommodate the Dutch Marechaussee requirements and not only for flights to/from the UK (except maybe onlinegar.com). Not sure why you get this “infected” warning. The SSL certificate is valid. Will do an extra scan of the server. Thanks for letting me know.
